WINDOW-LOCK.

Specification of Letters Patent.

Patented Dec. 20, 1910.

Application filed September 10, 1909. Serial No. 517,089.

To all whom "it may concern:

Be it known that I, FRANKLIN J MGCLAS- KEY, a resident of Millvaleborough, in the county of Allegheny and State of Pennsylvania, haveinvented a new and useful Improvement in VVindow-Locks; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof.

My invention relates to window locks, and has special reference to thelocking of sashes in metallic fire-proof constructions.

The object of my invention is to provide a cheap, simple and efficientsash lock which can be easily and quickly operated, and one in which theoperating parts of the same will not be exposed on the exterior of theframe or sash.

My invention consists, generally stated, in the novel arrangement,construction and combination of parts, as hereinafter more specificallyset forth and described and particularly pointed out in the claims.

To enable others skilled in the art to which 7 my invention appertainsto construct and use my improved sashlock, I will describe the same morefully, referring to the accompanying drawing, in which Figure l is aninterior side view of a window frame and sash having my improved lockapplied thereto. Fig. 2 is an enlarged vertical central section of thesame. Fig. 3 is a like view showing another form of a frame embodying myinvention applied thereto.

" ing, 1 represents the hollow window frame formed from sheet metal andhaving the head 2, meeting rail 2 and sill 3 therein which are connectedtogether by the jambs 4. Within the frame 1 are the hollow upper andlower sash 5 and 6 respectively, which are formed from sheet metal, andthe upper sash is shown as being of the pivoted type by being pivoted atits side rails 5 within the jambs l through the pivots 7 in the usualMounted upon'the head 2 of the frame 1 and lower rail 5 of the uppersash 5 are the swinging stop bars 8 and 8, each of which extends acrosssaid head and rail and is hinged or pivoted at its inner end around ascrew 9 passing loosely through each of said bars and through the bottomportions 2 and 5 of said head and. rail, as well as through a washer 10fitting against said portions and on the interior of said head and rail.The outerportion of the stop bars 8 and 8 in their locked positions areeach adapted to rest within a seat 11 formed in the upper faces of thetop rail 5 on the upper sash 5 and meeting rail 2 between said sash andthe lower sash 6 respectively, and such seats are inclined downwardlyand out wardly and have an upwardly projection or lug 11 formed by thewall portion at the outer ends of the said seats. WVhen the word frameis used in the claims for holding the pin 9, it is understood that italso refers to the bottoms of the sash rails. A tilting or swinginglever 12 is pivoted centrally inthe upper rail 5 of the upper sash 5, asat 12, and the inner end 13 of said lever extends through the inner faceof said rail, while the outer end 1% of the same is located within saidrail and is adapted to pass through a slot 14 inthe upper portion of 5of said sash, which forms the bottom of the seat 11 therein, and suchend 14 engages with the outer end of the bar 8. A hooked bar 15 isscrewed into the Quterend of the bar 8 and extends into the lower rail 5of the upper sash through the bottom 5 on said rail while a hooked bar16 by its hooked end 16 is adapted to engage withthe hook 15 on said bar15 and extends through the upper face on the inner side of the lowerrail 5 on the upper sash 5, where it is caught by one end of a chain 17connected to a hook 16" on such inner exposed end of the same. Thischain 17 passes through a ring 18 on the lower end of a bar 18, which isloosely hung at its up per end on the inner end 13 of the lever 12,while the other end of'such chain extends down from said hook so as tobe within easy reach of the operator, and if desired, such chain can becaught between the bifurcated arms 19 of a hook 19 extending out fromthe inner face of the uppper' rail 6 on the lower sash 6, which will actto hold such chain in position to hold the sash 5' in its openedposition and prevent the swaying, swinging or undue closing of the same.

In the operation of my improved window lock, the sash 5 is in its lockedposition in the frame 1, as shown in Figs. 1 and 2, and when it isdesired to unlock such sash, the

operator releases the chain 17 from between the arms 19 on the hook 19and pulls down upon the same, which will act to pull down the inner end12:3 on the pivoted lever 1:. and raise the outer end of the samethrough such chain being connected to the bar 18 loosely connected tosaid end 13 by such chain passing through the ring 18 on said bar. Whilesuch chain 17 is thus passing through the ring 18 on the bar 18 theportion of such chain between such ring and the hooked bar 16 is raised,while the other portion of the same in the hands of the operator isbeing lowered, so that the end 11 on the lever 12 in thus being raisedwill act to raise the outer end of the bar 8 on its pivot screws 9, andthe bar 16 being also raised through the rail 5 by the portion of thechain 17 connected thereto will also act to raise the outer end of thebar 8 on its pivot screws 9 by reason of such bar 16 being connected tothe hooked bar 15 on said outer end. As the bars 8 and 8' are thusraised within the seats 11 in the top rail 5" of the upper. sash 5 andin the meeting rail 2' between said sash and the lower sash 6, the outerends of said bars will be held above and free from the projections 11 onsaid rails and at the outer ends of said seats, so that said upper sashcan then be opened by being tilted or swung in the frame 1 on the pivots7, and when such sash is in its open position, the bars 8 and 8 are heldin position to be raised by the sash in closing by the inner ends ofsaid bars engaging with the bottom faces 2'' and 5 on the head 2 andsaid sash or by the inner wall of the holes in said bars engaging withthe pins 9, so that either such faces or the pins engaging with theholes in the bars will thereby form a holding means which will hold saidbars within said head and sash and thereby limit the downward movementof the same. Vhen it is desired to return the upper sash 5 to its closedand locked position in the frame 1, the operator releases the hold uponthe chain 17, which will raise the end 13 on the lever 12 and lower theend 1% thereon, and after such releasing the sash 5 can then be swung toits vertical position within the frame 1 on its pivots 7. In assumingsuch position the projections 11' on the sashes 5 and meeting rail 2will raise the outer ends of the bars 8 and 8, so that when the sash 5reaches its closed vertical position such ends will drop down by gravityin their seats 11 and behind said projections to lock the sash 5 in suchpo sition,

If desired, the lower sash (3 can be also swung in the frame 1 withupper swinging sash and can be locked within the stationary sill 3 ofsaid frame. and within the meeting rail 2 such as is shown in Fig. 3, inwhich case the seat 11 and projection 11 for the lower sash are locatedin the upper rail 6 of said sash and the upper swinging bar 8 for suchsash is mounted on the meeting rail 2 and below the seat 11 for thelower swinging bar 8 for the upper sash 5. In this case the lower seat11 for the sash 6 is formed in the upper face of the sill 3 and a pin 20held within the sill projects into said seat to be engaged by the outerend of the lower stop bar 8 on the lower rail (3 of said sash. The bars8 and 8 for locking the lower sash are operated in the same manner asthe bars 8 and 8 for the upper sash 5 and through another chain 17connected to said first named bars and through the means heretoforedescribed for said last named bars, such as to the bars 15 and 16 on thelower bar 8 on the sash 6 and the tilting lever 12 on the upper rail 6of said sash.

If desired, a single sash can be located in the frame 1 and be swungtherein by a locking means being located at the lower end of said sashfor engagement with the sill and another locking means located in thehead for engagement with the upper part of said sash, so that these twolocking means can be connected by a chain and operated as beforedescribed.

Various other modifications and changes in the manner of operating andapplying my improved window lock, design and lo cation of its operatingparts, and other changes in the same, may be resorted to, withoutdeparting from the spirit of the invention or sacrificing any of itsadvantages.

It will thus be seen that my improved window lock can be applied toswinging sashes 'or transoms of the pivoted, casement or hinged type,and various other forms of such devices, and can be operated withoutinterfering with any of the parts of the frame or sash. It will not beliable to get out of order or be subject to breakage and will not beexposed to the weather or to the eye. The device can be easily andconveniently applied to the frame or sash and when used on fire-proofconstructions it will be completely inclosed within the frame and sash.

Vhat I claim as my invention and desire to secure by Letters Patent isl. The combination of a window frame having a swinging sash therein, agravity bar on one of said members adapted to engage with a projectionon the other of said members to lock the sash in its closed position insaid frame, a headed pin extending downward from the frame for holdingsaid bar, and the inner end of said bar adapted to engage with saidholding means to limit the downward movement of said bar in the openposition of said sash.

2. The combination with a window frame having a swinging sash therein, agravity swinging stop bar on one of said members adapted to engage witha projection on the other of said members to lock the same in its closedposition in said frame, a headed pin extending downward from, the framefor holding said bar, and the inner end of said bar adapted to engagewith said holding means to limit the downward movement of said bar inthe open position of said sash.

3. The combination with a window frame having a swinging sash therein, amovable stop bar on one of said members adapted to be moved into a seatin the other one of said members and engage with a projection therein tolock said sash in its closed position in said frame, a headed pinextending downward from the frame for holding said bar, and the innerend of said bar adapted to engage with said holding means to limit thedownward movement of said bar in the open position of said sash.

In testimony whereof, I the said FRANK- LIN J MoCLAsKEY have hereuntoset my hand.
